# Slackbuild is released under the Dog-on-Fire License:
# If use of this script causes your dog to catch on fire,
# you agree to send me five dollars.  Or a picture
# of the dog on fire.
# Otherwise, you're on your own.  I've tested the script
# on my own computer, and it hasn't broken anything.
# So if it does it on your computer, that falls in
# the realm of "Not my problem."
#
# Of course, if you'll send a bug report to the above
# email address, I may be able to see what you did
# wrong and prevent it from happening in the future.
# In which case, I may just send YOU five dollars.

# Modified by the SlackBuilds.org project.
